Abstract

Ein Naßrasierapparat mit vibrierenden Klingen erbringt durch einen vom Klingensystem (1) entkoppelten Gleitschuh (2) eine verbesserte Schnittleistung, weil dieser nicht mitvibriert und somit die Gesichtshaut mit ihren Bartstoppeln, auf die der Gleitschuh beim Rasieren angedrückt wird, nahezu in Ruhe bleibt. <IMAGE>A wet shaver with vibrating blades provides improved cutting performance due to a sliding shoe (2) decoupled from the blade system (1), because it does not vibrate and therefore the facial skin with its beard stubble, onto which the sliding shoe is pressed while shaving, remains almost at rest. <IMAGE>

Description

Diese Aufgabe wird durch einen von den vibrierenden Klingen entkoppelten Gleitschuh gemäß Anspruch 1 gelöst. Weitere besondere Merkmale sind in die Unteransprüche 2-4 aufgenommen.This object is achieved by a sliding shoe decoupled from the vibrating blades. Further special features are included in sub-claims 2-4.

Wenn die Klingen nahezu unbehindert vom Gleitschuh vibrieren, dann vibrieren weder der Gleitschuh noch die Gesichtshaut mit, die Bartstoppeln bleiben somit in Ruhe und werden besser von den gegen sie vibrierenden Schneidkanten der Klingen abgetrennt. Die Entkopplung ist erfindungsgemäß so gelöst, daß bei Vibration der Klingen kein Prellgeräusch entsteht.When the blades are almost unhindered by the shoe vibrate, then neither the shoe nor the vibrate Facial skin with, so the stubble stays calm and become better from the cutting edges vibrating against them the blades severed. The decoupling is according to the invention so solved that when the blades vibrate no bouncing noise arises.

Ein Vorspannen der Haut vor den abzuschneidenden Bartstoppeln ist bei vibrierenden Klingen nicht erforderlich. Dagegen stellen sich vibrierende Klingensysteme als besonders hautschonend heraus, wenn die Gesichtshaut unmittelbar vor und hinter den Schnittkanten durch einen Gleitschuh gestützt und ruhig gestellt ist.Preloading the skin before cutting it Beard stubble is not necessary with vibrating blades. In contrast, vibrating blade systems pose as particularly gentle on the skin when the facial skin immediately in front of and behind the cut edges by a Is supported and immobilized.

Fig. 1: zeigt einen Gleitschuh (2) in Gestalt eines Röhrchens, in dessen Innern eine rund angeschmiegte, hauchdünne Klinge mit zwei Schnittkanten (1) unbeeinflußt vom Druck auf die Gesichtshaut longitudinal vibriert, der Gleitschuh dabei aber selbst und damit auch die von ihm berührte Gesichtshaut nahezu in Ruhe bleibt.Fig. 1: shows a slide shoe (2) in the form of a tube , inside which a round, gossamer-thin blade with two cut edges (1) vibrates longitudinally, unaffected by the pressure on the facial skin, but the slide shoe itself and thus also by him touched facial skin remains almost at rest.

Das optional auch langsame, vorsichtige Führen dieses Klingenblocks über die Gesichtshaut ermöglicht gegenüber dem 'Ratschziehen' einer Handrasur sogar erstmalig zwei sinnvolle Schnittrichtungen (Ziehen und Schieben, vorteilhaft bei Haarwirbeln oder im Normalfall ungünstig in Ziehrichtung des Klingenblocks wachsenden Barthaaren).The optional slow, careful driving of this Blade blocks across the facial skin allow opposite the 'ratcheting' of one hand shave even two for the first time sensible cutting directions (pulling and pushing, advantageous with hair vertebrae or normally unfavorable in Direction of the blade block of growing whiskers).

Fig. 2: zeigt einen Gleitschuh (2), der beweglich in die federnden Stege (6) der Klingenhalterung, bestehend aus bspw. drei vibrierenden runden Klingen-Kombinationen, angeschnappt ist, die sich beim Andrücken des Klingenblocks auf die Gesichtshaut bündig anpressen, ohne Druck auf ihn aber abgehoben bleiben und somit die Schnittkanten gegen Beschädigung oder gegen Verletzung beim Anfassen schützt.Fig. 2: shows a sliding shoe (2) which is movable into the resilient webs (6) of the blade holder, consisting of, for example, three vibrating round blade combinations, which are pressed flush against the facial skin when the blade block is pressed on without However, pressure on it remains raised and thus protects the cut edges against damage or against injury when touched.

Fig. 3: zeigt einen Klingenblock in dem mehrere Einzelklingen mit abgeknickten Schneidkanten eingesetzt und durch einen federnd vorgespannten und nur wenig mitschwingenden Gleitschuh (2) aus dünnem Federstahlblech in ihrer Halterung (12) mit federnden Schwinghaken (6) von unten gegenfixiert sind.Fig. 3: shows a blade block in which a plurality of individual blades used with bent cutting edges and resiliently biased by one and only little resonating shoe (2) against fixed made of thin spring steel sheet in its holder (12) with resilient oscillating hook (6) from below.

Fig. 4: zeigt einen federnden Gleitschuh (2), der am nur wenig vibrierenden Ansatz (11) des Schwinggebers aufgesteckt ist.Fig. 4: shows a resilient slide shoe (2), which is attached to the little vibrating attachment (11) of the transducer.

Fig. 5: zeigt einen Klingenblock in rechteckiger Form bei dem der Gleitschuh (2) mit einem federnden Steg (13) unter einer u-förmigen oder über einer gewölbten, länglichen Klinge gegen ihre Schneidkanten fixiert ist. Fig. 5: shows a block of blades in a rectangular shape in which the sliding block (2) with a resilient web (13) is fixed under a U-shaped or over a curved, elongated blade against its cutting edges.

Stand der Technik :State of the art :

Ultraschall-Naßrasierapparate mit hochfrequent vibrierenden Klingen sind bereits nach DE 90 05 626 U1, DE-OS 21 60 474, DE-OS 15 53 680, US 25 30 759, US 24 85 056, US 33 62 068, DT 2355791, DE 4026142 A1, Europa 0266080 A1, Europa 025930481 B1, G 68909835.8, G 9005626 und DE 196 21 215 A1 bekannt.Ultrasonic wet shavers with high-frequency vibrating Blades are already in accordance with DE 90 05 626 U1, DE-OS 21 60 474, DE-OS 15 53 680, US 25 30 759, US 24 85 056, US 33 62 068, DT 2355791, DE 4026142 A1, Europe 0266080 A1, Europe 025930481 B1, G 68909835.8, G 9005626 and DE 196 21 215 A1 known.

Trotz der vielen Ansätze wurden bisher diese Ultraschall-Rasierapparate vom Verbraucher nicht akzeptiert, weil der Schutzrahmen des Klingenblocks gemeinsam mit seinen fest mit ihm verbundenen Klingen vibrierte, wodurch die Gesichtshaut mit ihren Bartstoppeln ebenfalls in gleichsinnige Vibration versetzt wird und somit die Schnittleistung unbefriedigend bleibt.Despite the many approaches, these ultrasound shavers have so far been used not accepted by the consumer because of Protective frame of the blade block together with its fixed blades associated with it vibrated, causing the Facial skin with its stubble also in the same direction Vibration is offset and thus the cutting performance remains unsatisfactory.

Zudem erzeugt das Kribbeln der bisher mitvibrierenden Gesichtshaut beim Rasierenden aus Angst vor Verletzung eine instinktive Vorsicht und er drückt daher den Klingenblock zu schwach auf die Gesichtshaut, wodurch das angestrebt tiefe Abtrennen der Bartstoppeln unmittelbar an der Hautoberfläche ausbleibt.In addition, the tingling causes the vibrating so far Facial skin when shaving for fear of injury instinctive caution and he therefore closes the blade block weak on the facial skin, which is aimed at the deep Cut off the stubble immediately on the surface of the skin absent.

Bei mit Batterie betriebenen Ultraschall-Naßrasierapparaten ist die auf den Klingenblock zu übertragene Vibrationsleistung ohnehin begrenzt, sodaß es außerdem von Vorteil ist, wenn möglichst wenig Masse, also nur die Klingen und nicht der sie umgebende Schutzrahmen mit seiner Haut-Vorspannleiste und damit auch nicht die berührte Gesichtshaut mitvibriert.In the case of battery-operated ultrasound wet shavers the vibration power to be transmitted to the blade block limited anyway, so it's also an advantage if as little mass as possible, so only the blades and not the blades surrounding protective frame with its skin pretension bar and so that the touched facial skin does not vibrate.
